It is found in the Mesopelagic and bathypelagic zones, and is known to occur at depths of between 400 and 1, 400 metres.

Mesopelagic fish are often highly mobile, whereas bathypelagic fish are almost all lie-in-wait predators, normally expending little energy in movement.
33.
Bathypelagic fish have special adaptations to cope with these conditions they have slow metabolisms and unspecialized diets, being willing to eat anything that comes along.
34.
Bathypelagic fish are sedentary, adapted to outputting minimum energy in a habitat with very little food or available energy, not even sunlight, only bioluminescence.
35.
What little energy is available in the bathypelagic zone filters from above in the form of detritus, faecal material, and the occasional invertebrate or mesopelagic fish.
36.
The lesser known family, the Bentheuphausiidae, has only one species, " Bentheuphausia amblyops ", a bathypelagic krill living in deep waters below.
37.
Epipelagic fish occupy sunlit waters down to, mesopelagic fish occupying deeper twilight waters down to, and bathypelagic fish inhabiting the cold and pitch black depths below.
38.
Flabby benthopelagic fishes are like bathypelagic fishes; they have a reduced body mass, and low metabolic rates, expending minimal energy as they lie and wait to ambush prey.
39.
Recent studies have detected the presence of significant levels of dioxins in the commercial shrimp " Aristeus antennatus " and significant levels of persistent organic pollutants in mesopelagic and bathypelagic cephalopods

This fish, commonly known as the "'pink vent fish "', is associated with hydrothermal vents and cold seeps at bathypelagic depths in the East Pacific.
